elsa made 20,000 in taxable income last year. Suppose the income tax rate is 10% for the first 9,000 plus 16% for the amount over 9,000

The right response is B. It is the graph of f(x) scaled down by 11 units.

For any given value of x, the output of f(x) is subtracted by 11 to get the function g(x) = f(x) - 11.

The result is the same as the input for the function f(x) = x. Thus, if we take 11 out of the result, we get:

g(x) = f(x) - 11 = x - 11

In other words, the graph of g(x) is the graph of f(x), 11 units lower.

Thus, assertion B is the correct one. It is the graph of f(x) scaled down by 11 units.

Answer:

x = 13

Step-by-step explanation:

Let's simplify and solve for x:

4(x+56.5) = 30x - 112

First, we distribute the 4:

4x + 4(56.5) = 30x - 112

Simplifying the expression:

4x + 226 = 30x - 112

Now we move all the x terms to one side and all the constants to the other:

226 + 112 = 30x - 4x

338 = 26x

Finally, we solve for x by dividing both sides by 26:

x = 13

Therefore, the solution to the equation 4(x+56.5)=30x-112 is x = 13.

Answer:

x=9.94

Step-by-step explanation:

4x + 226 = 30x - 112
226+112 = 34x
338 = 34x
338/34=x
9.94=x

If the retailer pays the invoice within 20 days and takes the discount, the net amount due is $11,656.

The sale's "6/20, n/30" clause allows the retailer to choose between paying the invoice in full within 30 days or taking advantage of a 6% discount if they do it within 20 days. If the bill is paid by the 20th day, we can determine the net amount owed as follows:

Then, we multiply the invoice amount by the discount rate to determine the amount of the discount:

Discount: $744 ($12.400 x 0.06)

The amount owed if the discount is taken is then determined by deducting the discount from the invoice amount:

Discounted amount due: $12,400 - $744 = $11,656

The net amount owed is therefore $11,656 assuming the store pays the invoice within 20 days and applies the reduction.

Since the denominator of the expression (1 + 0.1t) cannot be zero, the domain of the model is between t = 0 and t = -10.

In order to identify the values of the independent variable x and acquire the domain, we simply solve the equation y = f(x). Simply put, x=g(y) will calculate the function's range after we identify g's domain (y).

(b) We must assess the model at t = 0 in order to determine the starting number of elk in the herd:

P = (10 + 3.3t)/(1 + 0.1t)

P = (10 + 3.3(0))/(1 + 0.1(0))

P = 10/1

P = 10

(c) We can easily enter the relevant values of t into the model to determine the populations of elk after 25, 59, and 113 years, then round the results to the nearest integer.

When t = 25:

P = (10 + 3.3t)/(1 + 0.1t)

P = (10 + 3.3(25))/(1 + 0.1(25))

P ≈ 47

When t = 59:

P = (10 + 3.3t)/(1 + 0.1t)

P = (10 + 3.3(59))/(1 + 0.1(59))

P ≈ 189

When t = 113:

P = (10 + 3.3t)/(1 + 0.1t)

P = (10 + 3.3(113))/(1 + 0.1(113))

P ≈ 458

(d) We can use the expression's limit as t approaches infinity to determine the expected population limit:

lim P as t → ∞ = lim (10 + 3.3t)/(1 + 0.1t) as t → ∞

Using L'Hopital's rule, we can find that the limit is equal to:

lim P as t → ∞ = lim 3.3/0.1 as t → ∞

The cost of framing for the masterpiece is $46.73.

To calculate the cost, we need to first determine the perimeter of the artwork.

Given the dimensions of the artwork, the perimeter is 100 + 100 + 70 + 70 = 340 inches.

The cost of framing is $4.95 per yard, so we need to convert the perimeter to yards.

To do this, we divide the perimeter by 36 inches since 1 yard equals 36 inches.

Thus, 340 inches divided by 36 inches equals 9.44 yards.

Therefore, the cost of framing the artwork will be 9.44 yards multiplied by $4.95 per yard, which equals $46.73.

About 420 visitors might go to the food pantry on an extremely cold day

What is the percentage?

Percentage refers to a way of expressing a number as a fraction of 100. It is often denoted by the symbol "%". For example, if 30 out of 100 students in a class are girls, the percentage of girls in the class is 30%. Percentages are commonly used in many fields, such as finance, statistics, and science, to express proportions, rates, and changes over time.

The problem states that on average, about 240 people visit the food pantry every day in search of groceries. To find out how many visitors might go to the food pantry on an extremely cold day, we need to use the given percentage increase.

The phrase "175% of the average amount" means that we need to find 175% of 240, which is the same as multiplying 240 by 1.75 (since 175% is the same as 1.75 as a decimal). Using the multiplication, we get:

175% of 240 = (175/100) * 240 = 420

So, on an extremely cold day, the number of visitors to the food pantry might be around 420.

Therefore, about 420 visitors might go to the food pantry on an extremely cold day.

Answer: Since Connor gets 69% of the money, Maria gets the remaining 31%:

100% - 69% = 31%

Let's first find out how much money Maria makes:

Maria's share = 31% of $595.54

Maria's share = 0.31 x $595.54

Maria's share = $184.61

Now, to find out how much Connor makes, we can subtract Maria's share from the total:

Connor's share = Total - Maria's share

Connor's share = $595.54 - $184.61

Connor's share = $410.93

Therefore, Connor makes about $410.93 (rounded to the nearest dollar).

Thus, using the matrix technique, the solutions to the simultaneous equations are x = -1 and y = 1.

A rectangular array of numbers or even other mathematical objects that can perform actions like addition and multiplication is known as a matrix. Matrices are widely used to describe systems of equations, transformations, and data in mathematics, physics, engineering, computer science, and many other disciplines. The individual matrix components are frequently identified by their row and column positions, and matrices have a predetermined number of rows and columns. There are numerous actions that can be carried out on matrices, including addition, subtraction, and multiplication by other matrices.

given

We can write the equations in matrix form as follows to answer the simultaneous equations 1x + 4y = 9 and 2x - 3y = 7 using the matrix method:

Then, on the left side of the equation, we can locate the inverse of the coefficient matrix:

| 1 4 |^-1 = 1/(-11) | -3 -4 |

|-2 -1 |

When we multiply both sides of the equation by the coefficient matrix's inverse, we obtain:

| x | | 1 4 |^-1 | 9 |

| x | | -3/11 -4/11 | | 9 |

| y | = | -2/11 -1/11 | x | 7 |

If we simplify, we get:

x = (-3/11)*9 + (-4/11)*7 = -1

y = (-2/11)

*9 + (-1/11)

*7 = 1

CI is calculated as (0.649 - 0.621) 1.812*sqrt(0.0872 + 0.0722)

CI = 0.028 ± 0.114

CI = (−0.086, 0.142)

What is line?

A one-dimensional geometric figure that consists of infinitely many points arranged in a straight path or direction.

In this case, we are reflecting across the line y = -2, which is two units below the x-axis. Therefore, the y-coordinate of each point in the preimage will be changed by 2 units after reflection.

The coordinates of L are (-1, -6), and after reflecting across y = -2, the y-coordinate will become

-6 + 2 = -4

Therefore, the image of L, L', will have coordinates (-1, -4).

Looking at the given options:

A. L'(-3, 6) - This point is not on the reflected line y=-2, so it cannot be the reflection of L.

B. OL'(-1,6) - This point is above the reflected line y=-2, so it cannot be the reflection of L.
